Abstract: A self-expanding stent is provided for introduction into a cavity of a human body. The stent has a tubular body which is radially expansible and axially retractable between a working state and a resting state. The tubular body has first and second plaited filaments which provide a middle portion of a first diameter and two flared end portions of increasingly larger diameter as they extend away from the middle portion. Each flared end portion has an axial length along a longitudinal axis of the stent which is greater than an axial length of the portion of minimal diameter. Preferably, the middle portion is a single location, with the diameter of the stent increasing in both directions from that location to the ends of the stent. Different shaped stents are disclosed, including stents having generatrices taking the form of line segments angled relative to the longitudinal axis, and generatrices taking the form of a hyperbola segment or a circle arc segment.

Title: Methods of making different additive-containing filaments
Inventor: JONES FRANK R
IPC: C08J3/22
Filed: 1996-12-03
Abstract: Methods of continuously producing sequential lengths of different additive-containing melt-spun filaments include continuously supplying a melt-spinnable polymeric host material to orifices of a spinneret and controllably dosing at least one dispersible additive concentrate systems containing a pigment in a liquid nonaqueous polymeric carrier to the melt flow of polymeric host material upstream of the spinneret orifices.  In such a manner, a first polymeric mixture of the dispersible additive concentrate system and the polymeric host material is obtaine which achieves an additive attribute.  During a first time  interval,  the  first mixture  is  extruded through  the spinneret orifices; and thereafter, during a second subsequent time interval,  the dosing of the at least one dispersible additive is changed so as to form a second mixture having a second additive attribute different from the first additive attribute  while  continuously  supplying  the  melt  flow  of polymeric host material to the spinneret orifices.  The melt-spun filaments will thus have a first length corresponding to the first additive attribute of the first mixture and a  second subsequent length  corresponding  to  the  second  additive attribute of the second mixture.   The methods and additives employed most preferably achieve Hunter Green Purge Values of between about 0.10 to about 1.40 sec/cm3.

Title: Coupling device connecting an unbalanced signal line to a balanced signal line
Inventor: DECRAMER JOHN E
IPC: H03H7/42
Filed: 1995-12-19
Abstract: Disclosed is a passive, highly efficient, low noise coupling device that includes a balun (14) and noise reduction circuitry uniquely configured for converting an unbalanced video signal on a 75 ohm transmission line or connector to a balanced signal on a 100 ohm transmission line or connector and vice versa. The device efficiently allows use of a 100 ohm unshielded twisted pair, such as a conventional telephone cable, for multiplex transmission of video signals or the like in the frequency range of 50 to 500 megahertz. The preferred embodiment has a circuit board with a 75 ohm unbalanced side and a 100 ohm balanced side separated by a balun having a toroid core with a very high permeability. A common mode choke (16) for noise rejection is inserted in the balanced side. The choke has a dual toroid core, one core of high permeability and one of low permeability, and has windings with a 100 ohm characteristic impedance. A common mode toroid shunt (18) on the device's balanced side provides further noise reduction. Circuit board traces connecting the components are impedance-matched to either the balanced side or the unbalanced side as appropriate.

Patent CA-2210144-A1 (CA)
Inventor: ROSS JOHN A F
IPC: H04B1/707
Filed: 1997-07-10
Abstract: L'invention concerne un procédé et un appareil de signalisation à spectre étalé, à référence transmise, à retard et corrélation et à conversion directe qui repose sur un circuit numérique à composants minimes au lieu de circuits analogiques de retard et à multiplicateurs. Le procédé permet une conversion RF en bande base et élimine la nécessité d'un étage de fréquence intermédiaire. Le récepteur comprend un convertisseur RF pour convertir un signal à spectre étalé à séquence directe en bande de base. Un convertisseur analogique-numérique échantillonne le signal de bande de base à une vitesse supérieure à la vitesse de segmentation du signal à spectre étalé à séquence directe. Un étage de retard couplé à la sortie du convertisseur analogique-numérique génère un signal retardé. Le circuit logique multiplicateur reçoit les signaux de sortie émis par le convertisseur analogique-numérique et l'étage de retard et, en réaction, génère des signaux de sortie de commande. Un compteur réactif aux signaux de sortie de commande augmente ou réduit un compte ou entame un nouveau cycle, en fonction des signaux de sortie de commande décodés.
